Capacitive Inventory Sensing for Real-Time Item Level Tracking

Solution Overview

Problem

Current inventory management systems rely on manual counting, which is time-consuming, labor-intensive, and often inaccurate, leading to delays in inventory tracking, forecasting issues, and increased costs, as well as potential losses in production and revenue.

Innovation Solution

A sensor-based system that uses capacitive sensors to automatically measure the level, weight, or volume of items in containers, bins, and pallets, communicating this data wirelessly to a data processing device for real-time inventory updates across a network, enabling accurate and efficient inventory management.

AI summary

A method includes automatically sensing a level of a number of items through a number of sensors, each of which corresponds to an item of the number of items, by measuring a change in an output parameter of the number of sensors as a consequence of placement of each corresponding item of the number of items directly or indirectly on the each of the number of sensors. The level is a quantity, a weight and/or a volume. The method also includes communicating a signal indicative of the level of the number of items through the number of sensors to a data processing device in response to the automatically sensed level of the number of items, and updating, through the data processing device, another data processing device associated with a consumer, a distributor and/or a supplier with the level of the number of items in accordance with the communicated signal.
